DOOSAN DP126 Series For Power Generation
Doosan Infracore Engine
DOOSAN DP126 SeriesFor Power Generation Doosan Infracore, which has been engaged in engine production and development since 1958, introduces a new generator engine.The newly introduced DP126 Series has been born with the two years of effort from Doosan Infracore, the company with excellent track record of designing superb engine design techniques.
When compared to other engines in its class, which are manufactured by competitors, it displays a higher output, excellent fuel efficiency, higher safety, and easier maintenance and is expected to become the key product from Doosan Infracore.

Increased output
DP126 Series is a mechanical engine that has global-level specific power, achieving the output that matches our previous V8 14.6L engine and 14L/12.4L engines from competitors.
Moreover, 50 / 60Hz conversion is possible freely without restriction of power output.
It is expected to display an additional output increase by 20% in the future when the electronic common rail type is developed.
Economic efficiency
Fuel consumptionDeveloped to have the lowest fuel consumption in its class.
Oil consumptionBy applying impactor as a standard, oil carryover has been minimized and the oil consumption has been decreased by 50% when compared to competitors in its class.
Improved oil pan size allows operation of 500 hours without oil replenishment and oil filter replacement.
In addition, by applying an anti-drain bowl shape and anti-drain back valve oil contamination is prevented during the oil replacement.
Easy maintenance
Application of auto tensioner
By automatically adjusting the tension on the belt without supervision or modification by a user, other auxiliary machinery, including the cooling fan, can operate smoothly.
Also, timely belt replacement can be judged through the inspection of the auto tensioner.

Easy maintenance
Application of Micro V-Belt
The Micro V-belt has superior bendability and additional frictional force when compared to existing V-belts on P158 engines, and the high-quality material increased the lifespan and functionality of the belt.
Enhanced durability
To enhance its durability, the rigidity of the main components, including the 4-valve all-in-one cylinder head, cylinder block, and crankshaft, are reinforced.
Furthermore, the durability was proven with 10,000-hour engine test.
Increased safety
Safety guards, such as belt cover, heat screen, and such, are installed to ensure the safety.
